WINDOW-WEIGHT.

SPECIFICATION forming part of Letters Patent No. 755,107, dated March22, 1904:. Application filed October 22, 1903. Serial No. 178,001. (Nomodel.) I

To all whom it may concern:

Be it known that 1, JOHN W. BRYANT, a citizen of the United States,residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful ImprovementsinWindow-VVeights; and Ido hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in'the art to which it appertains to make and use thesame.

My invention has for its especial object to provide -an improvedsupplemental windowweight, which may be applied to and removed from thesuspending cords or ropes'by lateral movements, all as will behereinafter more fully described.

The invention consists of the novel construction whereby thewindow-weight may be applied to or removed from the suspending-cord bylateral movements when'the rope is kinked at the proper point, but canneither be applied to-nor removed from the rope while it is drawn tautand straight.

The invention is illustrated in the accompanying drawings, wherein likecharacters indicate like parts throughout the several views.

Figure 1 is a view in side elevation, showing an ordinary window-weightand suspendingrope and showing several of my improved supplementalwindow-weights also applied to said rope. Fig. 2 is a perspective viewof one of my improved supplemental weights. Fig. 3 is a plan view of thesaid supplemental weight, and Fig. 4 is a horizontal section on the lineas m of Fig. 2.

The numeral 1 indicates an ordinary windowweight, and the numeral 2indicates the weightsuspending rope or cord, which rope is soon red tosaid weight in the usual or any suitable way.

The supplemental-weights 3 are preferably made cylindrical, althoughthey might take other forms, and when designed for use as window weightseach supplemental weight will usually be made to weigh about one-halfpound each. The said supplemental weight 3 is provided with a straightaxial passage or bore 4 of considerably greater diameter than the rope2. A curved slot 5 opens from the central bore 4 out of the peripheralportion of the said weight 3. This crooked slot 5 at its upper and lowerportions extends radially outward from the bore 4: in the same verticalplane; but the central portion of said slot radiates outward from thesaid bore on a line that diverges from the plane of the extremities ofsaid slot, as clearly shown in Figs. 3 and 4, wherein it will be notedthat at the central portion of the weight the surface of the bore 4 isleft intact between the points y and y. The portionbetween y and yextends across the circumferential space occupied by the upper and lowerextremities of the radial slot 5, and thus prevents the supplementalWeight from being removed from the rope as long as the rope is drawntaut or straight. The weight may, however, be very easily removed fromthe rope simply by giving the rope slack, so that it may kink, andhencepass laterally outward through the crooked slot 5. It is of courseevident that the supplemental weight is applied to the rope by kinkingthe rope and enteringthe same laterally into the slot 5. Thissupplemental weight,

while especially designed for use as a windowweight, is of coursecapable of a much more general use.

In hanging windows and other devices by the use of weights it almostalways happens that the weights which have been ordered will not exactlycounterbalance the window-sash. This is due, among other things, to thefact that the exact weight of a window-sash and its glass cannot alwaysbe determined in advance, since sash of the same size will varyconsiderable in weight. Hence it is very desirable to have an adjustableweight. After the sash has once been hung and the primary weight appliedto the rope untying of the rope from the primary weight for the purposeof adding supplemental weights is an action which is to be avoided, ifpossible. At the same time the supplemental weight or weights whenapplied must besecurely held against accidental displacement. As isevident, I have met these conditions by an extremely simple andefiicient device.

My improved supplemental weights will cost per pound approximately thesame as the is not parallel therewith, substantially as depresent simpleform of standard windowscribed. I weight. In testimony whereof I affixmy signature in What I claim, and desire to secure by Letpresence of twowitnesses. 5 ters Patent of the United States, is as follows: JOHN W.BRYANT.
